ProblemThe fluctuating quality of recovered paper is one of the greatest disruptive factors in the preparation of secondary fibre pulp in paper mills. The ash content, the content of tacky contaminants (stickies) and the deinkability of graphic papers vary depending on the composition of the recovered paper.A fluctuating ash content, for example, influences the strength of the finished paper product. Excessively high bale moisture means losses in purchasing. Charges with unusable materi-als cause recycling costs, massive losses in quality and reduce equipment availability.SolutionAn immediate check of the recovered paper quality in the receiv-ing area makes it possible to react promptly by lodging a com-plaint or by reducing the value of the delivery.

The PTS Paper Bale Sensor provides the necessary information regarding recovered paper quality. If the bales contain high-quality, homogeneous paper, its surface is checked. If the bales contain mixed paper, a lance probe allows the interior of the bale to be inspected.Measurement parameters• Moisture • Plastic • Ash • FibreEvaluation• Immediate calculation of quality parameters• Comparison with threshold values and immediate display of
